Representing a real estate investor and developer in litigation arising from a failed joint venture to acquire, own and operate a 50 percent tenant-in-common interest in fourteen valuable midtown Manhattan commercial properties. Dispute includes claims that our client's former partner breached a contribution agreement between the parties by selling the rights and interest in the acquisition to a third-party for its own benefit, misappropriating funds intended for joint venture purposes, and misappropriating a $46 million payment that it was not entitled to under the terms of the agreement.
